Overview

  • The Marine Corps accepted its 359th and final MV-22B on Tuesday, July 28, 2026, closing the service’s program of record and marking the end of new MV-22B procurement for the Corps.
  • With procurement finished, the service is shifting to sustainment and modernization work that includes improved nacelle wiring, standardized fleet configurations, a redesigned input quill assembly, and new proprotor gearboxes made from triple-melted refined steel.
  • Safety-driven limits remain in place for some aircraft, with a February 2023 flight-hour restriction on the input quill assembly credited with preventing further hard clutch engagements and other gearboxes still subject to component or hour thresholds.
  • The MV-22B has become central to Marine operations, flying more than 686,500 hours across 114 deployments and providing about 75% of the Corps’ rotary-wing assault lift, a role that shapes how Marines plan and move forces.
  • Production continues for other users and the future: the Navy will receive additional CMV-22s through fiscal 2028, the Air Force completed its CV-22 buys in 2025, and the Marine Corps has begun early work on a Next Generation Assault Support replacement while oversight and technical fixes continue.
